3 Claims.

This invention relates to improvements in chair seats and has referenceparticularly to a resilient edge construction for the front of the seat.

A chair seat ordinarily consists of a wood or 6 metal frame Supporting aplurality of spring units, either of the coil or flat non-sag type.

Upon this assembly rests the cushion. It has been found that greatercomfort can be afforded chair seats of this character by installing anespecially devised spring construction for the front of the seat anditis the object of this invention to provide a novel arrangement ofsprings along the front rail of the chair seat, whereby added re- 1accomplish the object of this invention by means of the embodimentthereof hereinafter de-. scribed, setforth in the ap'pen'dedclaims andillustratively exemplified in the accompanying 20 drawing, in which:

Figure 1 is a substantially'transverse section viewof a chair seat andcushion;

' Figure 2 is a perspective view of the. chair seat; showing the frontedgespring construction. 0 Referring to the drawing, ll denotes aboxlike seat comprising side and back rails and a fiat "depressed frontrail H, the latterbeing much broader than the sides and substantiallyone-half the height. The back portion of the rail is reinforced by meansof a web piece or block I! which is secured in pomtion against the innerface of the rail II by means of screws II. In the drawing, I have shownspaced fiat springs it disposed acrossifrom side to side of the seatrail ll, each spring comprising a zig-zag strand Mounted upright uponthe front rail. are a' number ofclosely adjacent spring units Ii, eachthereof comprising an internal spring coil indi- .vidually enclosed in acylindrical cloth casing l I,

45 010W at opposite ends. The top coil of each unit supported upon thefront rail I i is about level with the flat. springs l4 and a wire clipor tie piece I8 is' used to attach the upper coil of each unit to anadjacent angle of the Iraqi; fiat spring. 50 The entire seat isooveredat its top by a covering I! which is brought downwardly over thespring units It and is attached to the front rail Ii.

'lhe forwardi'face of the front rail II in the present instance iscovered by a skirt portion of the seat covering II. The seat or cushion22 comprises asprlngfllledpadunderlaidwithholr able because ordinarilythe front edge of a seat the nearest loop of said zig-zag spring.

or other suitable material. The covering 2| is perforated over its toppiece and the edges 22' are headed to provide an attractive finish. Theskirt is a depending portion of the sides and front of the covering 2!and a. bead 23 is formed in the material between the sides, front andskirt portion 20. The free under edge of the skirt,

' What I claim is: i

u 1. In a chair seat the combination of a frame having two side rails, afront rail of a height substantially less than that of said side rails,a zig-zag spring mounted won and extending be- 25 tween said side railsin a horizontal plane above the upper surface of said frOnt rail withthe front ends of its loops disposed adjacent a vertical plane throughthe rear edge of said front rail, a row of hdical springs supported onsaid front rail with their top coils substantially in the horizontalplane of said zig-zag spring, and means toconnect the top coilof each ofsaid helical springs with the forward end of the nearest loop of said"zig-zag spring.

2..A chair seat as claimed'in claim 1 comprising further additionalzig-zag springs mounted on and extending between said side rails inthehorizontal plane of the first mentioned zig-zag 4'springandrearwardlythereof. o
